Iontophoretic drug delivery system is viable drug delivery platform technology. Iontophoresis is an effective technique for physically facilitating transport of solutes across skin for both local and systemic effects. The principle distinguishing feature is the control afforded by iontophoresis and the dose can also be titrated for individual patients by adjusting current. It is believed to be future method of choice for the systemic delivery of protein and peptide drugs which normally can only be delivered by parenteral therapy. Iontophoretic drug delivery system is particularly desirable for drug that need prolonged administration at controlled plasma levels that basis make appropriateness to cardiovascular agents for transdermal development. Controlled zero order absorption, easy termination of drug delivery, easy to administration also support for popularity of iontophoretic delivery. This paper reviews the work on iontophoretic studies of cardiovascular agents in tabular form.
